| Abstract: | The major parameters of manufactured-sand gradation, grain shape, fineness modulus and others are determined by doing the test. According to the performance characteristics of manufactured-sand and the test of engineering practice, the concrete mix proportion can be made. The thesis proposes the main points that should be noted during the preparation of manufactured-sand concrete and construction. |
